Applictaon filed-October 21, 1916.Vv -Seria1`No.-126,8`28.1 i

To all whom t may "concern:

Be it known that I, FREDERICK A; EMER-l Ion, a citizen of the United States, residing at Oswego, -J-in the 'countyofOswego and State of New York, have inventedv certain new and useful 'Improvements lin Post-and- Bar Fences, of which the following is -a` I orportion between the grooves so far as they specification.' Y

This invention relates tol p ostand -bar fences. Its object is to produce an easily erectable fence without use of nails, screws, bolts or the like, except in each post where the threaded end of'a reinforcingrod holds a nut for clamping in place the concrete capv to hold in their properpositions the ends of either one orA two groups of bar ends and bar spacers; that Tis', one group of bar ends andv bar spacers atjone side of the post, or a group 4of barends and bar spacers at each side of a post. The posts and also the barsv hereinafter described may be made of any desired material, but in present practice I prefer to make'the posts and post caps ofconcrete and the bars andkbar spacers of wood.

part hereof,

Figure 1 is a top plan view,

Fig. 2 is a side elevation, and' Fig. :3 is a vertical lengthwise elevational view in section through a post at line 3-4-3 of Fig. 1'. v

Fig. 4 is a transverse sectional elevation at line 4-4 of Fig. 2, and shows the arrangement of the parallel and crossed bars and of the top rail. f n

Fig. 5 is a transverse sectional detail, enlarged, at line 5,-5 of Fig. 1, and showsthe bar and rail clamping means at the top of 'a4 post.

post caps. 'I I Fig. 7 is a transversesection at line .-7- 7 of Fig. 2 throughone-of-the posts toillustrate the air space preferably provided for in the post at the ends of the bars.

Fig. 8 is a perspective'view of one ofthe bar spacers, alloffwhich are of the same shape, but some of which are longer than others. v

In the drawings, each post 1 'is formed with lengthwise extending grooves 2, 2, one

at one and the other at the opposite side of the post, each groove being open at the top and extending part way toward the earthentrant foot portion' of the post. The grooves at their vertical bottoms-are prefer- Fig. 6 is an under-plan view of one ofthe ably shape to* provide air circulation y spaces at the ends ofthe bars and inneredges of thebar-spacers if"'ba`rs and bar-spacers are'ofwood. Theposts are shown of concrete, anda vertical reinforcing bar 3 extends preferably throughout "the entire length of the post in the centralsolid wall extend.- The bottom end groove is preferably` beveled upwardly and inwardly toward the vertical4 bottom or lengthwise extending bottom -forming shaped wall ofeach groove as a matter of convenience in assembly. For this purpose eachof the horizontal bars 5 has the upper and under corners of eachend beveled toward the lengthwise axis of the bar, as at 6, the bars as shown being rectangular in crosssection, and located edgewisewith their ends in the opposed grooves of two posts. The bar endsj are Hat and'do' not fill the shaped vertical air-circulation'` spaces formed Aby the shaped vertical bottom walls. Ifv the beveled shoulders were made horizontal, the undern corner. "portion of the lowermost bar would need to be straight and workmen wouldoften make mistakes in putting inthe bottom bar;lwhefreas by making all the horizontalbars alike lat-their 1ends and making the shoulders l upwardly and inwardly slanting, such mistakes in assemblage are avoided and any one ofthe horizontal bars may be properly used asthe horizontal bottom bar. While I have emphasized these two'details of my preferred" construction, I donot intendto limit thisinvention to such details, to wit the shaped vertical bottom walls for securing air .circulation and the slanted bottom end shouldersA of the grooves; and in other respects the particular construction as shown may. be varied without departure from the' invention.

Between eachen'd ofeachhorizontal bar 5 and the lcorresponding end offeach higher horizontal bar, spacers 7` are inserted in the post grooves, each end of eachspacer being shoulder 4 of each vbeveled at 8 in the dire'cti'on'-olfd the open through the horizontal bar ends, or through j.

any bar ends, or through any of the spacers, 'a're'required Two upper cross-bars 9 which are preferably, and as shown, bent past each other midway between their ends, may be used above the horizontal bars 5, and intermediate the uppermost horizontal bar 5 and a top horizontalclamp rail. rThe under corner of each cross-bar 9 is chamfered at 1U to rest flat on the top edge of the uppermost horizontal bar 5 and the upper corner of each cross-bar is chamfered at 11 to bear atly against the under edge of the' clamprail 12. The ends of the cross-bars 9 are located in the post grooves and the opposed corners `of the cross-bars are beveled at 6, similarly to the bevels 6 of the horizontal bars 5 for interlocking with the elongated upper spacers 7 which except for length are identical with the under spacers 7. lThe top or clamp rail grooves and its ends rest ony the chamfered upper corners 11. lts upper edge is socketefl in a lengthwise-extending groove 18 of a. horizontally disposed cap-board 14, the ends 15 of which overlap the ends of the clamp, rai-l 12 and rest on the post tops, eX- tending only part way across the post tops. The opposed ends 15 of two top clamp rails 12 are arranged to permit the upward eX- tension between and above them of the upper threaded end portion 16v of the upstanding reinforcing bar in a post. A post. cap 17l having a central bore 18, and in its flat bottom two alined recesses 19, fits on the u-p- A standing threaded end 1G and over the opposed ends of two opposed capy boards 14, and a clamp nut 2O on the end of the upstanding threaded end 16 clamps the whole assemblage firmly together without the' use of other fasteners than the nutsI and threaded ends 16 of the vertical reinforcing bars 3; but except for such fasteners, no fasteners are necessary, and my invention may be called a nailless fence. The interlocking spacers 7r serve in lieu of nails, bolts or screws for holding the ends of the bars'in place, and such spacers cannot work loose or out. The post-cap construction prevents the cap-board from turning and also prevents the post cap from turning whenY the clamping nut is screwed firmly down; and this arrangement tends to insure vthe cap from becoming fractured by undue strains brought on the cap board. In present practice, I prefer to make all the parts except the posts, post caps, reinforcing rods and nuts,

Copies of this patent may be obtained for five cents each,A by addressing the 12 has its ends in the postV of wood. The cap-boards are preferably convex von the upper surface in order better to shed water and to prevent them from cupping under the actionof moisture. Obviously all the bars 9 as well as the bars 5 may be horizontally disposed if desired; and any desired number of bars may be used.

What l claim is,-

1. The combination of a fence post hav- Ving oppositely disposed vertical bar-receiving grooves; an upstanding threaded clamp member; a series of bar ends in each groove; a series of spacers in each groove between the bar ends therein, suchy spacers interlock ing at their ends with the bar ends; top rails each havingan end in a post groove; for each top rail a horizontal cap-board, the opposed ends of the cap-boards bearing on the post top, and said clamp member passing upwardly between such opposed ends; a post-'cap having alined bottom grooves each of which fits on an end of a cap-board with an end wall of each groove opposed to an end of a cap-board, the cap having, a hole through it whereby the cap lits over said threaded clamp member; and a nut thereon and bea-ring against said cap', each end of eachV of said spacers being slanted in the direction o-f the open side of the bar-holding groove, and each interlocking bar havingl slanted corner portions bearing on and thereby interlocking with the slanted. ends of the spacers.

2. In post-and-rail fenceconstruction, the combination of a post 'provided at its upper end with an upstanding threaded projection and with a vertical groove for reception of rail ends and for reception of separable rail spacers; a series of rails corresponding ends of which are mounted in said groove; a series of spacers'located in said groove, one between each two opposed rail ends, each of said spacersl interlocking at each end with an end of a rail; and means for clamping the assembled rail ends and spacers demounrably in said groove; each end of eaclr of said spacers being slanted in the direction of the open side of the bar-holding groove, and each interlocking bar having slanted-corner portions bearing on and thereby interlocking with the slanted ends of the spacers.

In testimony whereof I have hereunto set my han-d. Y i FREDERICK A. EMERICK.
